OPTIMIZATION OF ACTIVATED SLUDGE PROCESS SYSTEM FOR DYE WASTEWATER

Treatment of textile wastewater or dye wastewater is little difficult suing biological treatment for wastewater like activated sludge process due to complex nature of the dye. This paper reports pre-feasibility study of activated sludge process for simulated dye waste removal. Activated sludge process involves biomass development, acclimatization if complex waste are to be treated. Here active biomass was developed from domestic sewage and then it was acclimatized for Navy Blue 3G dye and optimized mix system of 70-30 ratio (Dye effluent –sewage) has been suggested with 20 hr as optimum detention time. Optimized system shows 91% of average dye removal.
